maintenance schedule

romero1990 · 06-26-2021, 04:12 PM

It looks like our F25s are mainly CBS.
My '17 x28i is closing to 60K miles. So far the main works done are oil changes and filter changes, plus a new set of tires.
I do recognize 60K is a major mark to check and service. I wonder if folks have a list of things to work on at 60K for good?

A few items I am inspecting/planning.

1. spark plug
2. Akebono pads (CBS saying I got about 5K miles left on both front/rear pads).
3. Going to inspect rotors to see if they need replaced.
4. If I can find a reputable shop - front/rear diff/transfer case and trans fluid change.
5?

Yes, maintainence schedules are sort of long gone.

Here's couple of things I'd add to your list:

- Brake fluid flush/refill, if that's not been done - good idea to do it every 3 or so years; the fluid does absorb moisture over time.

- Brakes: best to remove a front and rear wheel so you can physically inspect the pads and rotors, measure thickness. Rotors have a minimum thickness stamped on them, as long as they measure at or above that value no need to change. Pads have wear sensors, you get alerted on the dashboard when a wear sensor is triggered; not long after that you definitely need to replace pads. CBS is really not reliable indicator regards pad wear - visual inspection is the best way to go.

- Transmission and Xfer case...you can find a shop; I had this done by independent Euro car shop at 75K miles, worth the expense if you're planning to keep the car long-term. Ditto for the differential fluids.

- Not a bad idea to drain/refill the coolant system if fluid is original; but you could let it go for another year or two. Always use BMW coolant mixed with distilled water.

- Inspect the serpentine belt for wear and the belt tensioner/idler pulley for smooth operation; belt & idler/tensioner should be good for near 100Kmiles.

Good luck/Bill

good call on the coolant and brake fluid Bill. I think both were done last year on my last free maintenance. it will be just the right time to do when 60K hits

You might check your records regards the coolant, these days I think BMW considers that fluid a Lifetime fill- might be it's only changed if there was some repair work done involving the cooling system.

and they won't even change it, they will just top off what spilled out during the repair

You should be able to check the pad thickness pretty easily. Just look between the wheel spokes at the pads themselves.

My X3 thinks mine need to be replaced but there's still 7 or so mm of pad material there which means I have 10's of 1,000's of miles left most likely.

As others have stated, the brake life indicator in iDrive should not be relied on. It literally is no more accurate than knocking on your neighbor's door and asking how many miles are left on your pads. It reads nothing. Just look at them visually through the wheel spokes or use a small mirror. If you want to be proactive you can add coil packs and belt to your list.

Mine has varied between 3100 and 4100 miles remaining for over 3 years. road trips (ie 200-500 miles), and it goes up. In town driving, works down. I think the last report from dealership was 7-8mm pads. I'm over 96k miles on car.

Are you saying those are the original pads? New pads are about 10mm, so 7mm at those miles would be a miracle unless you drive a lot of highway miles.

I've read somewhere that new pads are around 12mm, and you should consider replacing them when they get under 4mm, so I'm over half way through. Just looked with flashlight, and I'm guestimating under 1/4", which would be 6-7mm.

And I drive about 400 miles/month on the highway out of town. And until recently drove about 12 miles/day on the highway to where I worked.
